摘要:
The present disclosure provides method and systems for improving nanopore-based analyses of polymers. The disclosure provides methods for selectively modifying one or more monomeric subunit(s) of a kind a pre-analyte polymer that results polymer analyte with a modified subunit. The polymer analyte produces a detectable signal in a nanopore-based system. The detectable signal, and/or its deviation from a reference signal, indicates the location of the modified subunit in the polymer analyte and, thus, permits the identification of the subunit at that location in the original pre-analyte polymer.

摘要:
Provided is a system for detection of nucleic acid, the system comprising: (i) a detection apparatus, wherein the detection apparatus comprises one or more protein nanopores and (ii) an amplifier configured to amplify electrical signals generated at the nanopore and/or a computer or data acquisition circuit coupled to the detection apparatus to evaluate signals detected from the protein nanopore. In one aspect, the detection apparatus comprises a solid support with an array of solid-state nanopores and a plurality of lipid nanodiscs with protein nanopores, wherein the lipid nanodiscs are disposed on the solid support such that they form seals at the solid-state nanopores. In another aspect, the detection apparatus comprises one or more nanopores that are surrounded by a membrane, wherein each nanopore is tethered to an electrode. Also provided are methods of sequencing nucleic acids using the systems.
摘要:
A method for enriching a target nucleic acid comprising providing an endonuclease system having a crRNA or a derivative thereof, and a Cas protein or a variant thereof. The crRNA or the derivative thereof contains a target-specific nucleotide region substantially complementary to a region of the target nucleic acid; contacting the target nucleic acid with the endonuclease system to form a complex; and separating the complex and thereby enriching for the target nucleic acid.
